A machine of the above description has been lately invented by William R. Goulding, of New York ity, who has taken measures to secure a patent. It consists simply of a knife that may be adjusted to suit any thickness of bread that may be required to be cut, and of a guide bar connected to it by means of screws. These screws, which are for the purpose of adjusting the knife to the required width lor cutting the slice of bread, are fastened to the ends, and pass through the ears or projections of the guide bar, which are tapped to receive them. In order to obtain the requisite width, the screws are turned in a corresponding direction (to right or left), and the thickness of the slice of. bread is varied accordingly.
